C2C

Back on the bird place to say: if you’re in Oregon today, stop by the C2C booth at Watershed Festival, where we explore how ancient volcanic eruptions shaped climate and life. Volcanoes, Lava, and Life—words to live by! Feat. @VolcanoListener, @laurenrockdoc & Pedro Monarrez

The first of hopefully many papers from our @NSF funded @c2c_proj, suggesting that cryptic degassing driven by a rheologic phase transition in the crust (shutting off LIP eruptions) drives prolonged warming periods in Earth History. @magmatist @tamsinmather @bjwmills and others.

Our new @C2C_proj paper is out (and OA) in @NatureGeosci! nature.com/articles/s4156… tldr: We recognize prolonged climate warming intervals after multiple LIPs. We suggest CO2 release can continue from deep LIP plumbing systems long after surface volcanism wanes, driving warming

This road cut slices through near vent deposits from explosive (phreatomagmatic?) episodes of the Wapshilla Ridge member—at 40,000 km3, one of Earth’s largest eruptive events. Annotated outcrop sketch from this great field guide by Camp et al: pubs.usgs.gov/publication/si…

And here is the outcrop reveal…

What do you see? The C2C project explored this amazing (and complicated) outcrop with Oregon high school students. There’s an incredible story in these rocks…

Check out these humongous dikes lurking beneath the Columbia River Basalts (and meet the friendly horses who helped us haul our gear up to explore them)! Great field work with @VolcanoListener and the C2C team
